Title: Improvements relating to the carburizing of iron, steel and alloy steels
IPC: C23C8/66
Filed: 1937-03-30
Abstract: A carburizing compound for iron steel and alloy steels comprises carbonaceous material mixed with lime and a heavy metal oxide or a finely divided heavy metal and substantially no other energizers, the heavy metal being one which has an atomic weight between 50 and 60 such as nickel, iron, chromium, manganese vanadium and cobalt.  The carbonaceous material may be coal containing less than 4 per cent of ash, and usually not more than 6 per cent of lime is used in the mixture as well as not more than 2 per cent of iron oxide if used. The ingredients may be mixed together and compressed into pellets or the mixture of ingredients may be coked, and the product crushed and screened to provide fragments of a desired size.  In an example 100 parts of powdered carbon, such as charcoal or pitch coke dust are mixed with 5 parts of hydrated lime and 5 parts of finely powdered iron oxide, the mixture moulded into pellets with molasses as a binding agent. The pellets may be heated before use to char the molasses binder. Instead of heavy metal oxides or metal compounds of those metals which are reduced to oxides or the metals may be used and instead of lime, calcium carbonate, hydroxide or other calcium compound reducible to the oxide.

Title: Improvements in and relating to protective arrangements for electric power systems
IPC: H02H7/06
Filed: 1949-04-06
Abstract: 659,208. Running generators in parallel; automatic control systems for generators. BRITISH THOMSON-HOUSTON CO., Ltd. April 6, 1949, No. 9396. Convention date, April 21, 1948. [Class 38 (iv)] [Also in Group XXXVII] In a system having a number of compound wound D.C. generators connected in parallel and having equalizing connections and voltage regulators, relays are provided to give protection from reverse currents, high-resistance faults and over-voltage conditions (see Group XXXVII). The Figure shows the detailed arrangement for one generator, that for the other generators being identical and all relays being shown in their de-energized positions. Voltage regulation is provided by a regulator VR having a variable resistor 17 connected in series with the circuit of the shunt field 3. The regulator has two coils, a voltage coil 40 and a coil 29 connected in series with the equalizing connection 11, 28, 43, 31, &c. The coil 29 is arranged to assist the voltage coil 40 in increasing the resistance in the shunt field circuit if the current in the equalizing connection is flowing towards the associated generator, i.e. if the associated generator is tending to generate a high voltage and is producing more current than the other generators. In this event, the effect of the coil 29 is to tend to reduce the voltage of the generator and so aid in balancing the load. To prevent a reduction in the voltage of the system should one generator be driven at a low speed, a resistance R1 is connected in the equalizing connection of the associated generator when this generator is disconnected by the action of reverse-current relays. This resistance R1 causes a reduction of the current in the equalizing circuit and reduces the effect of the coils 29 of the regulators of the other generators. The equalizing connection to a generator may be opened by a manual switch 36.
Patent GB-790373-A (GB)
Title: Improvements in or relating to diphenolic acids
IPC: C07C51/347
Filed: 1955-03-31
Abstract: The invention comprises acids having the general formula: <FORM:0790373/IV (b)/1> wherein R represents a parahydroxyphenyl radical or a mono- or dialkyl substituted ortho or para-hydroxyphenyl radical and wherein R1 represents a mono- or dialkyl substituted ortho- or parahydroxyphenyl radical and the method of preparation thereof which comprises condensing in the presence of a non-oxidizing mineral acid, levulinic acid with mono- or dialkyl substituted ortho-, meta, or p-hydroxybenzene, or with a mixture of any of said hydroxybenzenes with phenol.  Phenolic starting materials mentioned include ortho, meta and para cresols, propyl, butyl, amyl and ethyl phenols, xylenols, diethyl, dipropyl, dibutyl and diamyl phenols. The products may be purified by decantation or distillation followed by vacuum distillation to leave a crude diphenolic acid which may be further purified by dissolving an alkali or aqueous sodium or potassium carbonate, filtering the solution and acidifying to precipitate the diphenolic acids.  In examples: diphenolic acids are prepared by reacting levulinic acid in the presence of hydrochloric acid with meta-cresol (I); para-cresol (II); a mixture of ortho- and meta-cresols (III); a mixture of meta- and para-cresols (IV); a mixture of phenol and ortho cresol (V); technical xylenol containing 3.5-xylenol (VI); and ortho-amyl phenol (VII).  The products may be esterified e.g. with a partial ester of a polyhydric alcohol such as may be formed from glycerol and linseed oil fatty acids or may be reacted with polyamines to form amides which are further reacted with e.g. resin acids.  Such amides and esters and the diphenolic acids may be reacted with aldehydes to form resins (see Group IV (a)).ALSO:Resins are obtained by reacting acids of the general formula: <FORM:0790373/IV (a)/1> where R represents a para-hydroxyphenyl radical or a mono- or dialkyl substituted ortho-or para-hydroxyphenyl radical and wherein R1 represents a mono- or dialkyl substituted ortho-or para-hydroxyphenyl radical (see Group IV (b)) with formaldehyde optionally in the presence of other phenols. The carboxylic groups may be esterified, e.g. with a partial ester of a polyhydric alcohol such as glycerol with linseed oil fatty acids, or may be converted to amido groups by reaction with polyamines which may be further reacted with resin acids or unsaturated oil acids.  A product which forms films or stoving on steel plates is obtained by condensing ortho- and meta-cresol with levulinic acid in the presence of hydrogen chloride, heatin the acid produced with linseed oil fatty acids and pentaerythritol in the presence of xylene, adding paraformaldehyde, oxalic acid and xylene to the product, heating the mixture to distil off water and xylene and dissolving the residue in a mixture of butyl acetate, butyl alcohol and methyl ethyl ketone.

Abstract: 472,833. Control of A.C. and D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd.,LIDDIARD, H. W. C., PETCH, jun., T. H., and CROFTS, J. W. March 30, 1936, No. 9409. [Class 38 (iii)] Regenerative and non-regenerative braking.- The generator of a Ward-Leonard system, particularly for use with winding engines, is driven by an induction motor which is excited with direct or alternating current when the normal supply thereto is broken so that it may act as a braking alternator by loading it on to a resistance, preferably the starting resistance of the induction motor. The Ward-Leonard generator 2 and exciters 3, 4, 5, are driven by an induction motor 1 started by closing a switch 12, auxiliary contact 12a of which energizes the coil 18b of a pilot contactor 18 whereby contactors 14, 15, 16, 17 are closed successively and automatically to reduce step-by-step the resistance 20 in the rotor circuit. During regenerative braking the induction motor acts as an asynchronous generator when its speed exceeds synchronous speed and returns power to the supply 11. Should the supply fail or switch 12 be opened, however, the contactor coils 14b .... 18b, fed directly or through a transformer 19 from the supply 11 are de-energized to insert the resistance 20 in circuit with the rotor of the induction 'motor, and the stator is excited with direct current from the exciter 5 through contactor 21 normally held open by coil 21b whereby the induction motor runs as an alternator loaded on to the resistance 20. The exciter 3 supplies the field 7 of the generator 2 through a Ward-Leonard regulator 8 and the exciter 4 supplies the excitation of the exciter 5 and the motor 6. The exciter 5 may alternatively be self-excited. A portion only of the resistance 20 may be used during regenerative braking or additional resistance may be used, the insertion thereof in circuit being controlled by contactor 21. Specification 434,668 is referred to.
